My hp 7150 printer has ink problems.

My hp 7150 printer won't print. The ink cartridge lite keeps blinking. I've replaced both cartridges (57 & 56). I've cleaned the contacts 3 times. I've turned it off, then on, holding the power button and clicking the resume button 4 times. I've reset the clutch. I even offered to have it's child!!! Nothing has worked.What can I do. I can't afford to buy another printer.HELP!!!!
